Study on Impact Performance of Energy Absorbing Structures under Horizontal Offset Loading

Severe Impact on the Behavior of Energy Absorbing Cylindrical Base in Frontal Impact

In this paper, the vibration characteristics of multi-layer shell that internal and external surfaces with a layer of piezoelectric sensor and actuator is investigated. The backrest shell laminated with simple analytical method to evaluate and the results were compared with results obtained by other researchers. The numerical solution methods (GDQ) for shells with piezoelectric layers and plain...

Experimental Study on Performance of Fiber Concrete-filled Tube Columns under Axial Loading

There have been great developments in the area of civil engineering in the recent few decades and among these, construction and material innovation are quite prominent. Steel-concrete composite construction has emerged as one of the fastest methods of construction. Even though considerable research efforts on conventional reinforced concrete columns have been executed prior to now, concrete fil...

The application of energy-absorbing structures on side impact protection systems

This paper presents a system to improve the protection to the occupants of a World Rally Championship Car in case of a side impact involving a tree collision using energy absorbing structures. An outline of the immediate events after the car crash into a tree are provided followed by an analysis of a typical standard rollcage, then the design criteria and features of a carefully selected design...

Effect of Corner Bluntness on Energy Absorbing Capability of Non-circular Metallic Tubes Subjected to Axial Impact

The energy absorbing capability is one of the most important aspects of crushing behavior of a structure subjected to axial impact. In this paper, a simple practical method is introduced to enhance the crushing behavior of this kind of structure. The axial impact of metallic energy absorbing thin-walled tubes with special shaped cross-section is simulated using LS-DYNA software. The effect of c...
